Rail steel is a high quality steel that has been recycled from railroad rails. Railroad rails are made of high carbon steel to withstand many years of massive weight from trains full of cargo. When railroad steel is recycled it is heated and re-rolled. This process decreases the size of the metal grains which increases resiliency.
Galvanized
Galvanized steel is steel that has been dipped in molten zinc to protect against corrosion. During the galvanizing process the zinc reacts with the iron in the steel to form alloy layers of zinc and iron. The outer layer is pure metallic zinc. Iron will rust very quickly; the zinc layers protect the iron from the elements that cause corrosion.
Carbon Steel
Carbon steel is made from two main elements, carbon and iron along with some magnesium. Carbon is the principal hardening and strengthening agent in steel. T-posts for barbed wire can be formed from cast carbon steel. Cast carbon steel is a 'C' grade material that contains a small amount of magnesium. The combination of carbon and magnesium give the steel strength, durability and weldability.
